All magicians should take a few acting classes. They show you the importance of a script , rehearsal and gives you flight time in front of audience that are not there to see magic

A few? Acting is more important than the tricks you perform. "A magician is an actor playing the role of a great magician" - Robert Houdin.

The word "great", which you have inexplicably added, is not part of the original Houdin statement (which is usually used out of context, as you have done here). However, if you choose to edit a famous quote then please don't also attribute it as if it was the original - that's just bad form.

If you must embellish a quote it's only proper to preface it by saying, "To paraphrase Robert Houdin...". Doing otherwise grates on those of us who prefer the reporting of magic history to be accurate.
